Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42436, here are decompositions:

3 + 42433 = 42436
29 + 42407 = 42436
113 + 42323 = 42436
137 + 42299 = 42436
179 + 42257 = 42436
197 + 42239 = 42436
227 + 42209 = 42436
239 + 42197 = 42436

Showing the first eight; more decompositions exist.
